Benefits of technology

The present invention provides a method and apparatus for controlling printing that can print on both sides of a medium simultaneously. This is achieved by dividing a first page of print data into multiple pieces and selecting one piece from each page to print on both sides of the medium. The result is a method and apparatus that can print over a plurality of media with a single print job.

Problems solved by technology

However, the poster printing function provided in the conventional printers only supports single-sided printing, and printers having both a double-sided printing function and the poster printing function have not been realized.

Embodiment Construction

[0037]Referring now to the drawings, descriptions will be provided below for a printer having a function of simultaneously realizing both poster printing and double-sided printing, and a method for controlling the printer, according to preferred embodiments of the present invention.

[Configuration of Printing System]

[0038]FIG. 1 is a block diagram showing a configuration of a printing system according to one embodiment of the present invention. As apparent from FIG. 1, the printing system according to this embodiment is so configured that a host computer 3000 and a printer 1500 are connected with each other via a bi-directional interface. Unless otherwise specified, the present invention is applicable to any of a stand-alone device, a system comprising a plurality of devices, or a system capable of printing processing connected via a network such as a LAN or WAN, as long as both the poster print function and double-sided print function of the present invention can be realized simulta...

Abstract

Poster printing and double-sided printing are realized concurrently by controlling an order of outputting pages for a divided image. A printer prints two consecutive pages of print data on both sides of a sheet of paper, and a host computer generates print data such that each page of print data is enlarged and divided and resultant data is printed on a plurality of media. A first page of print data is divided into a predetermined number of pieces in accordance with the number of sheets of print paper, and a second page of print data is divided in the same manner. Respective pieces of print data for the first and second pages are selected from the pieces of print data. Then, the selected pieces of print data for the first and second pages are printed on front and back sides, respectively, of a medium.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a technique for controlling printing in which an image is enlarged and divided so that it is printed over a plurality of media.BACKGROUND OF THE INVENTION[0002]Some printers or printing systems of today have been known for having a print enlargement function (hereinafter, referred to as a “poster printing function”) of enlarging and dividing an image on a page so that a resultant image is printed over several sheets of paper. With this function, an output of the enlarged image can be obtained by combining sheets of paper delivered in an order according to a manner of dividing the image.[0003]However, the poster printing function provided in the conventional printers only supports single-sided printing, and printers having both a double-sided printing function and the poster printing function have not been realized. This is probably because an arrangement of papers on which a divided image is printed is different between fr...
